All credits to the people who defined the unlocking method, which is a much more tedious work than implementing it as an application. Please don't hesitate to thank them.

Unlock is immediate and doesn't require reboot, and the app doesn't depend on any external tool (like Busybox) except root.

Crucial data is backed-up before any operation, however automatic restoration is not yet available inside the app.I will write it it many of you encounter issues.So don't freak out, even in worst case the app should not be able to bring any permanent damage.

Note that if I'm careful when writing software this one is provided without any kind of warranty or support.
